RNA
The version of RNA that has an anti-codon and delivers the proper amino acid to the ribosome to make a protein.
What is tRNA?
The process of making a duplicate strand of DNA.
What is DNA Replication?
The scientist that first took an image of DNA using X-ray crystallography.
A mutation is actually a change in
What is DNA?
The bacteria studied to better understand how gene regulation works in prokaryotes.
What is E. coli?
The job of RNA.
What is making proteins?
The nucleotide that is found exclusively in a DNA strand.
What is Thymine?
These scientists studied viruses to determine that DNA does indeed carry heritable genetic material while eliminating that proteins do.
Who is Alfred Hershey and Martha Chase?
A change in a single nucleotide in a codon that results in the same amino acid being added to the primary protein sequence.
What is a silent mutation?
This enzyme helps to transcribe the gene on the DNA.
What is RNA polymerase?
Location in the cell where a cell biologist would find rRNA.
What is the cytoplasm?
A section of DNA that contains instructions for making a protein.
This scientist developed the current accepted Theory of Evolution by natural selection, but had no idea that DNA existed.
Who is Charles Darwin?
A change in a codon by insertion or deletion that changes the reading frame in every codon downstream from the mutation.
What is a frameshift mutation?
The area on an operon where the RNA Polymerase will get on the gene.
What is the promoter?
The version of RNA that could be found in the nucleus.
What is mRNA?
A 3 nucleotide sequence on a gene that helps to obtain the proper amino acid later in translation.
What is a codon?
These 2 American scientists, aided by being able to see an image of DNA that was not theirs, constructed the first, accepted model of DNA.
Who are Watson and Crick?
This percentage of mutations are either silent or helpful.
What is 30%?
The form of regulation where the repressor allows the RNA Polymerase to get on when a certain chemical, like lactose, is present.
What is positive regulation?
Portions of non-protein coding sections of mRNA that are removed prior to the strand leaving the nucleus to go to the ribosome.
What are introns?
The part of the cell cycle where DNA replication occurs.
What is Interphase, or S Phase of Interphase?
Marcus Pembrey found conclusive evidence that genes have "switches" that can be turned on and off by environmental stressors. Pembrey's findings are critical in the development of this science.
What is Epigenetics?
A chromosomal mutation where the portion of the chromosome, exchanged during "crossing over", is reversed in its orientation.
What is inversion?
The proteins that allow RNA Polynerase to get on at the promotor and hold it in place until transcription begins.
What are transcription factors?
